CVE-2025-68759

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: rtl818x: Fix potential memory leaks in rtl8180_init_rx_ring()<br /> <br /> In rtl8180_init_rx_ring(), memory is allocated for skb packets and DMA<br /> allocations in a loop. When an allocation fails, the previously<br /> successful allocations are not freed on exit.<br /> <br /> Fix that by jumping to err_free_rings label on error, which calls<br /> rtl8180_free_rx_ring() to free the allocations. Remove the free of<br /> rx_ring in rtl8180_init_rx_ring() error path, and set the freed<br /> priv-&gt;rx_buf entry to null, to avoid double free.
